-SYNTAX
-add [MOVES|$ID1|@ID1] $ID2
-
-DESCRIPTION
-Appends either MOVES, the scramble memorized under $ID1 or the output sequence
-memorized under @ID1 at the end of the scramble memorized under $ID2. If none
-of MOVES, $ID1 or @ID1 is specified, the user will be asked to type the moves.
-Menmonic: "add x to y" or just "add to y".
-
-EXAMPLES
-add $1
-  The user is required to type the moves that will be appended to $1.
-add F R B $1
-  Appends the moves F R B to scramble $1. Now scramble $1 ends with F R B.

-change $ID1 [MOVES|$ID2|@ID2]
-
-DESCRIPTION
-Changes the scramble $ID1 to either MOVES, the scramble $ID2, the output @ID2
-or, if none is specified, the moves entered by the user. The scramble that was
-memorized under $ID1 is then lost.
-Mnemonic: "change x to y", or just "change x".
-
-EXAMPLES
-change $1
-  The user is required to type the moves that will replace $1.
-change $2 $3
-  Saves the scramble that was saved under $3 in $2. Now $2 and $3 are the same
-  scrambles, and the old $2 is lost.
-change $1 U R
-  Saves U R as scramble $1.

-DESCRIPTION
-Solves CO for a given scramble. A scramble can be given as last argument of the
-command, or an ID of a saved scramble can be provided. If none of the two is
-given, a prompt will ask the user to input a new scramble.
-
-OPTIONS
-axis={fb,rl,ud}    Specify the axis for the CO. One to three axes can be given,
-                   comma separated, no spaces.
-                   Default: CO on any of the three axis (omitting the option is

-SYNTAX
-dr [OPTIONS] [MOVES|$ID|@ID]
-
-DESCRIPTION
-Solves DR for a given scramble. A scramble can be given as last argument of the
-command, or an ID of a saved scramble can be provided. If none of the two is
-given, a prompt will ask the user to input a new scramble.
-If the option "from" is given (see below), it solves DR from an EO (if edges
-are oriented) without breaking that EO.
-The first time this command is called without the option from (and, to some
-extent, also the first time it is called with the option from), nissy loads
-some pruning tables that were not loaded on startup, causing a small but
-noticeable delay.
-
-OPTIONS
-axis={fb,rl,ud}    Specify the axis for the DR. One to three axes can be given,
-                   comma separated, no spaces.
-                   Default: DR on any of the three axis (omitting the option is
-                   the same as specifying axis=fb,rl,ud).
-b=N                Specify a bound for the number of moves. N must be a number.
-                   Default value: 20.
-h                  Show hidden DRs.
-                   Default, if an DR ending in e.g. R is shown, the equivalent
-                   one ending in R' is hidden.
-from {fb|rl|ud}    Solve DR from the specified EO, which must be solved,
-                   without breaking the EO.
-niss               Use NISS. It works only if solving DR from EO.
-                   Default: does not use NISS.
-n=N                Specify a maximum number of EOs to be output. N must be a
-                   number.
-                   Default value: 1.
-
-EXAMPLES
-dr from rl axis=ud $1
-  Finds optimal DR on ud, starting from EO on rl, for the first saved scramble.
-
-dr niss from fb n=10 m=6 F2 R L B' F D U' R2 L' F D B
-  Finds up to 10 DRs of length at most 6 from EO on fb, possibly using NISS.
-

-*******************************************************************************
-********************* NISSY: a cube solver and FMC helper *********************
-*******************************************************************************
-
-If you just want to solve the cube, type 'solve' followed by the scramble. This
-will not always give you an optimal solution, unless it is 10 moves or less or
-you use the "o" option. Finding the optimal solution might take very long if it
-is 16 moves or more, especially for the first time.
-
-Now the fun stuff. With nissy you can save and manipulate move sequences, for
-example:
-
-nissy-# save R' U' F
-$1:     R' U' F
-nissy-# add L2D' $1
-$1:     R' U' F L2 D'
-
-You can then ask nissy to solve certain substepson a saved scramble:
-
-nissy-# eo axis=rl $1
-@1:     U D F' R (4)
-
-And of course it uses also NISS, if you ask:
-
-nissy-# eo niss axis=rl $1
-@1:     (R) (1)
-
-Notice that the sequences you save are marked with a $, while the "output"
-sequences are marked with @. The difference between these two type of sequences
-is that those marked with @ are temporary and get lost once you get new output.
-Most commands accept as input either a move sequence typed out, a $-sequence or
-a @-sequence. For example, you can however save a @-sequence and make it
-persistent:
-
-nissy-# save @1
-$2:     (R)
-
-Nissy also understands NISS. Let's see a more complicated example where you
-save a scramble, ask for some EOs (using NISS) and then a DR on inverse:
-
-nissy-# save R' U' F R U R2 F2 R2 D R2 U L2 U R2 D2 B' D U' R D R' D U2 F2 R' U' F
-$3:     R' U' F R U R2 F2 R2 D R2 U L2 U R2 D2 B' D U' R D R' D U2 F2 R' U' F 
-nissy-# eo n=10 niss axis=fb,rl $3
-Found 10 results.
-@1:     (U' L B D F) (5)
-@2:     (U' L B' D F) (5)
-@3:     (L B U D F) (5)
-@4:     (L B' U D F) (5)
-@5:     R U B U L (5)
-@6:     R U' L (B L) (5)
-@7:     R U' B U L (5)
-@8:     R L (L B L) (5)
-@9:     R (U2 D' F R) (5)
-@10:    R (U2 F D' R) (5)
-nissy-# add @6 $3
-$3:     R' U' F R U R2 F2 R2 D R2 U L2 U R2 D2 B' D U' R D R' D U2 F2 R' U' F R U' L (B L) 
-nissy-# unniss $3

-nissy-# invert @1

-nissy-# dr from rl $5
-@1:     F2 U D2 F' B D B (7)
-nissy-# 
-
-If you ask nissy to solve a substep (or the whole cube) using a sequence with
-NISS as scramble, it will first un-NISS it (but without saving the unNISSed
-scramble anywhere):
-
-print $3
-$3:     R' U' F R U R2 F2 R2 D R2 U L2 U R2 D2 B' D U' R D R' D U2 F2 R' U' F R U' L (B L)

-
-Nissy knows how to solve certain common sub-steps for DR (or Thistlethwaite /
-Kociemba algorithms). For now it does know more common speedsolving methods.
-
-For a full list of commands type "help". For a more detailed help on a specific
-command, type "help (command)". The help pages can also be found in the docs
-folder.
-
-If you want to report a bug (I'm sure there are many!) or give a suggestion,
-you can send an email to sebastiano.tronto@gmail.com.
-
-Have fun!

-print [$ID|@ID]
-
-DESCRIPTION
-Prints memorized sequences. If no argument is given, it prints all memorized
-scrambles ($ only). If $ID or @ID is specified, it only prints the relative
-memorized sequence.
-
-EXAMPLES
-print
-  Prints a list of all memorized scrambles (only $).
-print $2
-  Prints the second memorized scramble.

-eo [OPTIONS] [MOVES|$ID|@ID]
-
-DESCRIPTION
-Looks for non-optimal subsequences and replaces them to shorten the given
-sequence. By default it tries to shorten every subsequence of up to 10 moves,
-but this can be change with the "b" option.
-It outputs at most 10 equivalent optimal sequences for each replaceable part.
-
-OPTIONS
-b=N                Finds non-optimal subsequences of up to N moves.
-
-EXAMPLES
-replace D2 F' D2 U2 F' L2 R2 U' D B2 D B2 U B2 F L2 R' F' D U' 
-  Produces the following output:
-Replace [ R2 U' D B2 D B2 ] (moves 7-12) with: [ D R2 D U' ] (-6+4)
-Replace [ R2 U' D B2 D B2 U ] (moves 7-13) with: [ D R2 D ] (-7+3)

-save [MOVES|@ID|$ID]
-
-DESCRIPTION
-Memorizes the scramble specified by MOVES, given as input or temporarily saved
-as @ID, where ID is a number ('help nissy' for for more on IDs). If an $ID is
-given, it makes a copy of the scramble. An identifier of the form $ID, where ID

-solve [MOVES|$ID|@ID]
-
-DESCRIPTION
-Solves the given scramble, which can be given as a sequence of moves or as $ID
-or @ID. If none is given, the user can type it on the next line.
-The algorithm first tries to find a short (<=10 moves) solution, and then
-switches to a 2-step algorithm (unless the option "o" is specified, in which
-case it keeps looking for an optimal solution).
-The first time it uses the 2-step algorithm it needs to load some tables, which
-can take a few seconds. It runs much faster after that. If the option "o" is
-specified, the first time it loads some large tables, which can take a minute
-or two.
-
-OPTIONS
-b=N                Only looks for solutions up to N moves.
-n=N                Tries to find multiple solutions, at most N. Multiple
-                   Solutions will only be found if they are <=10 moves.
-o                  Looks for optimal solution.
-
-
-EXAMPLES
-solve R' U' F
-  Solves the scramble R' U' F.
-solve o b=14 $1
-  Tries to solve the scramble $1 optimally, but stops if no solution of 14
-  moves or shorter is found.
-solve n=16 R L' U2 R' L F2
-  Finds the 16 shortest solutions for the scramble above.
